Vertical profiles of temperature trends

The workshop on vertical profiles of temperature trends, held 13-17 September 2004, covered a broad range of topics from the latest advances in observational climate records and climate models through efforts to achieve a process-based understanding of the underlying physical mechanisms driving climate change. Four working groups focused on specific problems that make it a challenge to obtain accurate vertical profiles of temperature trends and to understand their physical causes. Key points of each discussion include observational temperature datasets and climate models, constraining uncertainty by considering nontemperature variables, the stratosphere's role in tropospheric temperature evolution, and improving both historical and future climate records.
